and arei provided:through the. housings errd l walls IA andrl5"ioreapoommodatingtthe uides. The ameanstpmyided fon-movingstheeggsialong the track and cleansing the said eggs, consists in the providingor a pair of revolving spirally coiled cylindrical brushes, 36 and 3|,and mounting the said brushes on suitable shai'ts 3t and 35-,respectively, which shafts are revolvably supported in suitablebearings, 40 and 4|, respectiveiy, which are fixed in the end walls ofthe housing. The said spirally coiled brushes are positioned straddlethe track 28 and in parallelism one with the other as shown to advantagein rigs. l, 2 and 4, whereby the eggs are caused to be moved along thetrack and thoroughly cleansed during the revolvable movement of thebrushes. The outer end portions of the said brushes are preferablytapered as indicated at 36 and 57 to facilitate the admitting andreleasing oi the eggs to and from the track 28. The said bearings 40 and4| are retained in adjustable position by the cap screws 42 extendingthrough the s ots 43, whereby the distance between the brushes can bevaried in case of wear.

The means, provided for imparting revolvable movement to the brushescomprises a motor 44 connected to the said brushes in any suitablemanner. The speed of the drive pulley 45 is reduced in any suitablemanner to cause the brushes to revolve at the desired speed. The numeral45 designates a housing enclosing a conventional reduction gearmechanism for reducing the speed of the drive shaft 41. Numerals 48 and4e designate V-shaped pulleys fixed on the outer end portions of thebrush shafts 38 and 39, respectively, for accommodating a V-belt 50, asshown to advantage in Figs. 3 and 6. A suitable fan 52 is fixed on thesaid drive shaft 41 for blowing air through the bottom 5|, of the tray33, which bottom is preferably formed of a wire screen as illustrated inFigs. 1 and 6. The said motor and fan are supported on a suitable frame53. A baffle plate 54 is preferably provided for deflecting air to thetray. The dryer fan 52 can be positioned in any desired location toproperly dry the eggs in the most efiicient manner. For example, thesaid fan can be positioned between the gear reduction mechanism in thehousing 46 and the motor 44, or the motor can be moved closer to thehousing frame and the shaft of the motor extended and the fan positionedon the opposite end of the motor. be placed beneath thecleaner insteadvof below the dryer desired.

The side portions of the track 28 are grooved as indicated at 55 and 56in Fig. 7 which grooves fit slidably on horizontal flange portions 51and 58 provided on the track supporting members as shown to advantage inFig. 2. The vertical flange portions of the track supporting members 29and 30 are formed with vertically elongated holes 59 for receivingsuitable bolts or screws 60, whereby the said supporting members 29 and30 and track thereon are vertically adjustable. This adjustable featureenables the center of the egg or other object placed on the track toalways be slightly below the center of the brush axis, thereby giving aslight downward thrust tothe egg being cleaned on the track and thuspreventing the egg from coming out on top.

It will be seen to advantage in Fig. 3 that the brush members arerevolved in the same direction and also to advantage in Fig. 4 that bothof the brushes are spirally coiled in the same direction. The egg orother'objectpl'aced on the track between the brushes is thus pusheddownwardly on one side by one brush and lifted upwardly on the Thisentire unit can opposite side by the other brush and at the same timeconveyed longitudinally along the track. The egg is thus automaticallyrevolved many times causing the entire surface thereof to come intocontact with the revolving brushes in its course of travel through themachine. The brushes also keep the eggs aligned, enabling the eggs totravel straight throughout the entire length of the machine regardlessof which end of the egg is inserted, thereby preventing the egg fromturning end over end which would cause breakage and disturbance of theair cell. All sizes of eggs are readily cleaned. The brushes areself-cleaning, as centrifugal force removes any dirt or foreignsubstance from the brushes that have been removed from the eggs. Anelongated resilient finger 6| extends through the opening 34 in thehousing end member [4 and is secured to said member to lightly press theeggs downwardly on the track when starting the eggs through the brushes.Although the said brushes are spiraled in the same direction, thespirals can run in opposite directions if desired.

From the foregoing description taken in conjunction with theaccompanying drawings, it will be obvious that when an egg is placed onthe front guide 3| and is caught between the tapered end portions 36 and31 of the revolving brushes as shown in Figs. 1 and 2, the spirallycoiled brushes will push the egg along the track 28 to the outlet guide32. During the movement of the eggs along the said track, water from theoverhead pipe 22 will fall through the opening 24 to the eggs, wherebythe revolving brushes will thoroughly cleanse the eggs. It will be notedthat the said pipe is apertured for only a part of its full length,whereby the flow of water is stopped a short distance from the outletguide 32, enabling the revolving brushes to wipe the eggs before theyare released to the tray 33, where they are thoroughly dried by airblown from the fan 55 through the screened bottom of the tray. The eggswill automatically turn and roll through the said outlet guide 32 asshown to advantage in Fig. 2.

" ing eggs and the like, comprising a frame, a pair of elongatedcircular brush members revolvably supported thereon and arranged inparallelism and in proximity to each other, a track removably supportedon the frame and positioned between the brush members and below thecenters thereof for carrying the eggs, the said track being verticallyadjustable for enabling eggs of different sizes to be carried in thecorrect height with respect to the centers of the brush members, meansfor guiding the eggs to the track, an apertured water supply pipepositioned above the track and in parallelism therewith for enablingwater to fall on the eggs and brush members, the said brush membersbeing formed with spirally coiled brushes that are spiraled in the samedirection and means for revolving the brushes in" the same direction,whereby the eggs are revolved transversely on the track and movedlongitudinally along the track simultaneously.

2. A device of the character described for washing eggs and the like,comprising a frame, a pair of elongated circular brushes revolvablysupported thereon and arranged in parallelism and in proximity with eachother, means for revolving the brushes, said brushes being revolved inthe same direction, whereby the eggs are revolved, an elongatedstationary track positioned between the brushes and below the horizontalcenters thereof for carrying the eggs, means for guiding the eggs to thefront end portions of the brushes, said front end portions of thebrushes being tapered for receiving the eggs, the said brushes beingspirally coiled in the same direction, whereby the eggs are moved alongthe stationary track, an apertured water supply pipe positioned abovethe track and in alignment therewith for providing water on the eggs andcausing the eggs to be washed during their move- 6 ment along the track,a tray positioned at the rear end portion of the track for receiving thewashed eggs and a fan revolved with the brushes for drying the washedeggs in the tray.
